    vm: use __func__ for the correct function name
    
    In fee2a2fa39834d8d5eaa981298fce9d2ed31546d the KASSERTs in
    vm_page_unwire_noq() changed from "vm_page_unwire" to "vm_page_unref".
    While the former no longer was part of that function the latter does
    not exist as a function and is highly confusing when hit when using
    tools to lookup the functions and not doing a full-text search.
    Use %s __func__ for printing the function name, as that will do the
    right thing as code moves around and functions get renamed.
    
    Hit:    while debugging a wired page leak with linuxkpi/iwlwifi
